When J.C. is force-dancing with Brooke, she is struggling against him, and has her hands in and on her purse, retrieving her gun in the close-up. The next frame is a long-shot and she has one hand around the back of J.C.'s neck.
When Brooke MacKenzie faints in Jonathan's arms, she is still holding the cobra's head up and away from her body. A person who really faints would go limp in the arms.
In J.C.'s very first transformation in the taxi, instead of seeing the black panther jump out of its window, the animal is seen jumping from a wooden dresser. Random, and clearly shot indoors, whereas the panther is then supposed to be roaming the streets of NYC.
When the truck is overturned and the bad guys escape, MacKenzie's partner says, "MacKenzie, come back here, these guys have a machine gun." But he tells her to come back before she has had a chance to move so that she is still in place when he says, "Come back here."
